Top 5 Methods to Reset an Unknown or Forgotten Bios Password

BIOS is
a kind of software situated as a chip in the motherboard of your computer. It
is necessary to create a Bios password because it is able to stop someone booting
up your computer system or making changes in your computer. But you may come
cross the similar problem to “I made a password to get into my BIOS. How do I
get into my BIOS if I can't remember my password?” There is no need to worry.
There are many known ways to reset an unknown Bios password. Here I will share
5 effective methods with you:

Method 1: Reset Lost Bios Password by Removing CMOS Battery

Removing
the CMOS battery is the simplest way to remove a BIOS password. A computer will
remember its settings and keep the time even when it is turned off and
unplugged because these parts are powered by small battery inside the computer
called a CMOS battery. If we pull out this battery, the computer will forget a lot
of its hardware settings, including its BIOS password. Please follow the
instructions below:

Take out
the CMOS battery and wait 10 – 25 minutes before putting it back in. The reason
for this wait is because the computer can still store power in its capacitors
even though everything is unplugged. The waiting period allows enough time for
them to discharge. Plug everything back in, power up the computer and enter the
BIOS again. If everything went well there should be no more password. In some
cases, if you get weird error messages during boot up now, you will need to go
to “Load BIOS Defaults” in BIOS and save the changes to fix them.

If this
method didn’t work, try one of the methods below.

Note: This
should not be performed on Laptops if you are not experienced working with
laptop hardware. Make sure to power down the computer, unplug the power cables
and unplug any USB devices if they are powered. The computer must not be able
to get power from anywhere for this to work.

Method 2: Use Motherboard Jumper to Remove Forgotten
Bios Password

Almost
all motherboards contain a jumper that can clear all CMOS settings including the
BIOS password. The location of this jumper varies depending upon the
motherboard brand. You should read your motherboard manual to check its
location. If you don't have the manual then look for the jumpers near the CMOS
battery. Most of the manufacturers label the jumper as CLR, CLEAR, CLEAR CMOS,
etc.

When you
find the jumper, look carefully. There will be 3 pins and the jumper will be
joining the center pin to either left or right pin. What you need to do, is
remove the jumper and join the center pin to the opposite pin. e.g. if the
jumper joins center pin to left pin, then remove it and join center pin to
right pin. Now wait for a few seconds and then again remove the jumper and join
the center pin to left pin.

Note: Make
sure to turn the PC off before opening the cabinet and resetting the jumper.

Method 5: With Backdoor BIOS Password

It is
said that many computer manufacturers create backdoor passwords for their own
technicians to use so they can access the BIOS when the hardware is being
serviced. Here are some backdoor bios passwords that have been reported:
